COTTON- GRADEB.

Specification of Letters Patent.

Application filedjune 7, 1909. Serial No. 500,624.

T 0 all whom it may concern:

lle it, known that l LEMI'AL A. GREENE, a citizen of the United States.residing at Grcenville, in the county of (ircenville and State of SouthCarolina, have invented certain new and useful Improvements inCotton-Graders: and I do hereby declare the following to be a full.clear, and exact description of the invention, such as will 011-. ableothers skilled in the art to which it appert aius to make and use thesame.

M y invention relates to cotton graders ot' the type shown and describedin U. S. Patent No. 499,358, issued on June 13, 189?). and No. 935,149issued September 28, 1909,

wherein a variety of samples of cotton of known quality are arried in acase under a transparent cover which maybe extended beyond saidcase sothat a sample of unknown quality may be placed below it and comparedwith those in the case.

The case disclosed in the-patents referred to is capable of convenientlycarrying only a limited number of samples. If it is desired to have moresamples, it would be necessary to lengthen the case which would tend tomake it inconvenientto handle.

The principal objects of my present invention are to provide forcarrying a large number of samples of determined grades; to make thedevice more compact; and to arrange the samples so that a quantity ofcotton of unknown grade may simultaneously be compared with a largenumber of samles of predetermined grade.

. The invention consists primarily of a case containing a receptacle forreceiving a sample of cotton of unknown grade, and a plurality ofcompartments arranged around the receptacle. A

The invention also consists of the generic and specific features ofconstruction and arrangement of parts, substantially as hereinafterdescribed and claimed.

In the accompanying drawing illustrating two embodiments of myinvention, Figure 1 is a plan view of a cotton grader of rectangular{form constructed in accordance with my invention; Fig. 2 is a centrallongitudinal section of the grader shown in Fig.

1. and. Figs. 3 and 4 are similar views of a circular form of grader.

In Figs. 1 and 2 of the drawing, 1 desig- 4 if iised, conforms to thesha nates a case which is made rect-angular'in form and contains thecompartments 2 arranged around an opening 3 which is pretcrably withouta bottom. The compartments 2, each of which is intended to contain asample of cotton of determined grade and of a grade different from thatof the other compartments, and the opening 3 are preferably though notnecessarily covered by a. transparent cover 4. which if desired may 'beof niagnifyingglass.

A transparent cover admits of samples in the case being viewed withoutopening the con'ipartmcnts. and also protects said Samples from dust orother foreign substances which would change their appearance if allowedto collect on them. Again, if it is desired to seal the *ases so thatthe samples contained therein cannot be removed or changed thetransparent cover. may be permanently attached to the casing for thispurpose.

The construction illustrated in Figs. 3 and l: involves a circular case1 containing radial compartments 2 arranged around a circular opening 3.The transparentcover e of the case and preferably extends over t eopening 3 as well as over the various compartments.

Itis dilticult to determine the grade of a sample of cotton when thesample is to be compared with cotton of various predetermined gradeswhich is subject to dilter'ent lights or conditions of light. Inasmuchas by my'device. the cotton of known grades and the sample to be testedare compactly held. they are all in the same light and therefore anaccurate comparison is easily made. I

The greater facility and convenience in handling either of the forms ofcotton Patented Mar. 22, Milt).

Having thus described my invention, Wbzfl; I claim as new, and desire tosecure by Let tors Potent, is:-

1., A. cotton grader comprising; a case hovixig on ogenimg therein, arm?a series-oi comartments for containing samples of cotton surrounding theopening.

esases partments being :n'ymnged in close pr imit to the opening, hoththe case and open- 'mg eing covered by transparent material. 5. A.cotton grader compnsing av case hav ing a bottozmess opening therein,and u series of compartments for containing samples of cotton sumouningthe opening.

6, A comm grader comprising a case having a bottomless opening therein,and a series of compartmem's for containing Sam ples of cottonsurrounding the opening, both the opening and the compartments beingcovered. by transgmrentmaterial.

in testlmoiny whereof, I aifix my sign ture, in presence of twowitnesses.
